DETAILED DESCRIPTION

[0028] Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase "in an embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily all referring to a common set of embodiments, of the application, that are "in an embodiment." It is explicitly contemplated that embodiments described herein can be combined with each other in their individual aspects.

[0029] The embodiment of the present application provides a landscape ecological floating island based on aquatic plant cultivation, like Figures 1-10As shown, the landscape ecological floating island based on aquatic plant cultivation includes: a floating island main body, including a floating island plate 1 and a floating box 35 fixed at the bottom thereof; a mounting rack 2 fixed on the floating island plate 1, wherein a placing rack 3 is arranged on the mounting rack 2, and the placing rack 3 is provided with a lifting mechanism for driving the lifting thereof; a cultivation basket 4 arranged on the placing rack 3, for containing planting materials for cultivating aquatic plants; a shell 5 fixed on one side of the mounting rack 2, wherein a trimming mechanism for trimming the root system of the aquatic plants is arranged in the shell 5; the trimming mechanism includes a movable trimming shell 6 and a cutter head 7 arranged in the trimming shell 6, wherein the trimming shell 6 is provided with a translation mechanism for driving the lateral movement thereof, and the cutter head 7 is provided with a rotary driving mechanism; wherein the cultivation basket 4 is switched between a water culture position and a trimming position through the lifting movement of the lifting machine, and the cutter head 7 reaches the trimming position at the bottom of the cultivation basket 4 through the translation movement of the trimming shell 6.

[0030] In the embodiment, the placing rack 3 drives the cultivation basket 4 to move up and down by starting the lifting mechanism to drive the movement of the placing rack 3, so that the cultivation basket 4 is switched between the water culture position and the trimming position. When the root system needs to be trimmed, the cultivation basket 4 is lifted to the trimming position, and then the translation mechanism drives the trimming shell 6 to move laterally, so that the cutter head 7 in the trimming shell 6 reaches the trimming position at the bottom of the cultivation basket 4, and finally the rotary driving mechanism is started to drive the cutter head 7 to rotate, so as to trim the excessive root system of the aquatic plants.

[0031] The landscape ecological floating island changes the traditional manual trimming mode through the automatic trimming mode. The staff does not need to frequently climb onto the floating island to manually operate, so that the labor intensity is reduced, the labor cost is saved, and the work efficiency of the root system trimming management of the aquatic plants is improved.

[0032] In addition, timely trimming of the excessive and dense root system can effectively reduce the additional weight of the floating island caused by the growth of the root system, so as to enhance the stability of the floating island, avoid the change of the water flow field caused by the excessive growth of the root system and the adverse effects on the habitat environment of aquatic organisms, and help to maintain the balance of the water ecological system.

[0033] In the further preferred embodiment of the present application, the rotating driving mechanism comprises: a rotating shaft 14 assembled in the trimming shell 6 through a bearing bracket, the top end of the rotating shaft 14 being fixedly connected with the cutter head 7; a motor 8 fixed on the mounting frame 2; a spline tube 9 assembled on the mounting frame 2 through a bearing seat, the spline tube 9 being fixed with first bevel gears 10 that are in mesh with each other on the output shaft of the motor 8 for transmission; the spline tube 9 drives the rotating shaft 14 to rotate through a first transmission mechanism, the first transmission mechanism comprising: a first transmission rod 11 assembled on the inner wall of the mounting frame 2 through a bearing seat, the top end of the first transmission rod 11 being fixed with second bevel gears 12 that are in mesh with each other on the spline tube 9 for transmission; third bevel gears 13 fixed on the bottom end of the first transmission rod 11; a second transmission rod 15 assembled on the outer wall of the trimming shell 6 through a bearing seat, the top end of the second transmission rod 15 being fixed with fourth bevel gears 16 that can mesh with the third bevel gears 13; a third transmission rod 17 assembled in the trimming shell 6 through a bearing, fifth bevel gears 18 fixed on the second transmission rod 15 and the third transmission rod 17 and in mesh with each other; and sixth bevel gears 19 fixed on the bottom end of the third transmission rod 17 and the rotating shaft 14 and in mesh with each other.

[0034] In the present embodiment, the motor 8 is started, the first bevel gears 10 on the output shaft of the motor 8 drive the first bevel gears 10 on the spline tube 9 to rotate, and initial power transmission is achieved. After the spline tube 9 rotates, the second bevel gears 12 drive the first transmission rod 11 to rotate, and the third bevel gears 13 at the bottom end of the first transmission rod 11 rotate accordingly. When the trimming shell 6 moves to a designated position, the third bevel gears 13 mesh with the fourth bevel gears 16 at the top end of the second transmission rod 15, and power is transmitted into the trimming shell 6. Then, the second transmission rod 15 drives the third transmission rod 17 to rotate through the fifth bevel gears 18, and the third transmission rod 17 drives the rotating shaft 14 to rotate through the sixth bevel gears 19, thereby driving the cutter head 7 fixedly connected with the top end of the rotating shaft 14 to rotate, and completing the trimming work on the root system of aquatic plants.

[0035] The rotating driving mechanism adopts a multi-stage bevel gear transmission mode, utilizes the meshing transmission of bevel gears to transmit the power of the motor 8 to the cutter head 7, ensures the stable rotation of the cutter head 7, provides continuous power for root system trimming, and guarantees the smooth progress of the trimming work; cooperates with the lifting of the whole floating island and the translation mechanism of the trimming shell to perfect the automatic trimming system of the floating island. Manual operation of trimming tools is not needed, which reduces the labor intensity.

[0036] The lifting mechanism comprises a first screw rod 20 assembled in a bearing on the inner wall of one side of the mounting frame 2, the first screw rod 20 is threaded through the placing rack 3, a guide rod 21 fixed on the bearing, the guide rod 21 is threaded through the placing rack 3, the first screw rod 20 is driven by the motor 8, the first screw rod 20 is driven to rotate by the spline tube 9 matched with the clutch mechanism, the clutch mechanism comprises an electric telescopic rod 22 fixed on the mounting frame 2, an assembly plate 23 is fixed on the output rod of the electric telescopic rod 22, a spline rod 24 is assembled on the assembly plate 23 in a bearing, one end of the spline rod 24 penetrates through the spline tube 9, a seventh bevel gear 25 and an eighth bevel gear 26 fixed on the spline rod 24 and the top end of the first screw rod 20 respectively can be engaged.

[0037] In the embodiment, when it is necessary to adjust the position of the placing rack 3, the electric telescopic rod 22 is started, the output rod of the electric telescopic rod 22 drives the assembly plate 23 to move, so that the seventh bevel gear 25 on the spline rod 24 and the eighth bevel gear 26 on the top end of the first screw rod 20 are engaged with each other. Then the motor 8 is started, power is transmitted to the spline rod 24 through the spline tube 9, and the first screw rod 20 is driven to rotate by the engaged bevel gears. Since the first screw rod 20 is threaded through the placing rack 3, the placing rack 3 moves up and down along the guide rod 21 when the first screw rod 20 rotates, and the guide rod 21 ensures that the placing rack 3 moves stably, so that the cultivation basket 4 is switched between the water planting position and the pruning position.

[0038] The lifting mechanism uses the electric telescopic rod 22 and the bevel gear clutch structure to flexibly switch and transmit power. The motor 8 is used as a single power source, and the spline tube 9, the spline rod 24 and other components are matched to accurately distribute power to the first screw rod 20, so that the floating island structure is simplified, energy consumption is reduced, and the lifting operation of the placing rack 3 is more stable and reliable.

[0039] In the further preferred embodiment of the application, the translation mechanism comprises a second screw rod 27 assembled in a bearing in the housing 5, a sleeve plate 28 threaded on the second screw rod 27, a base frame 29 fixed on the sleeve plate 28, the base frame 29 is fixedly connected with the pruning shell 6 through a connecting block, a guide plate 30 fixed in the housing 5 and penetrating through the sleeve plate 28 at one end, the second screw rod 27 is driven by a second transmission mechanism, the second transmission mechanism comprises a fourth transmission rod 31 assembled in a bearing in the mounting frame 2, a ninth bevel gear 32 and a tenth bevel gear 33 fixed on the top end of the spline rod 24 and the fourth transmission rod 31 respectively and can be engaged, and an eleventh bevel gear 34 fixed on the bottom end of the fourth transmission rod 31 and the second screw rod 27 and can be engaged.

[0040] In the embodiment, when the pruning shell 6 needs to be moved to a suitable pruning position, the electric telescopic rod 22 first adjusts the position of the spline rod 24, so that the ninth bevel gear 32 on the spline rod 24 is engaged with the tenth bevel gear 33 at the top end of the fourth transmission rod 31. After the motor 8 is started, power is transmitted to the fourth transmission rod 31 through the spline tube 9 and the spline rod 24, and the eleventh bevel gear 34 at the bottom end of the fourth transmission rod 31 drives the second screw rod 27 to rotate. Since the sleeve plate 28 is threadedly sleeved on the second screw rod 27 and can only move along the guide plate 30 under the limitation of the guide plate 30, when the second screw rod 27 rotates, the sleeve plate 28 will drive the base frame 29 and the pruning shell 6 connected thereto to move transversely along the guide plate 30 until the cutter head 7 in the pruning shell 6 reaches the pruning position at the bottom of the cultivation basket 4.

[0041] The translation mechanism combines screw rod transmission and bevel gear transmission to construct a stable transverse movement driving system. With the motor 8 as a unified power source, power is efficiently transmitted to the second screw rod 27 through the engagement transmission of the spline rod 24 and each bevel gear, without the need for additional complex power equipment, thereby simplifying the mechanical structure of the floating island. Meanwhile, the screw rod transmission cooperates with the guide plate 30 to ensure the stability and accuracy of the translation process of the pruning shell 6, so that the cutter head 7 can be reliably moved to the target position.

[0042] In a further preferred embodiment of the present application, the bottom of the floating island plate 1 is fixed with an assembly frame 39, the bottom of the assembly frame 39 is fixed with a metal chain 40, and the bottom end of the metal chain 40 is fixedly connected with a positioning anchor 41.

[0043] In the embodiment, when installing the landscape ecological floating island, the positioning anchor 41 is placed at a suitable position at the bottom of the water body and connected with the bottom of the floating island plate 1 through the assembly frame 39 and the metal chain 40. The metal chain 40 has a certain flexibility and can adapt to the fluctuation of the water body and the slight shaking of the floating island. When the water body generates water flow or wind wave, the positioning anchor 41 pulls the metal chain 40 by virtue of its own weight and the grip on the water bottom, and the metal chain 40 further stabilizes the floating island plate 1 through the assembly frame 39, so as to fix the entire floating island in the predetermined area and prevent the floating island from drifting with the water flow.

[0044] The positioning structure adopts the combination of the assembly frame 39, the metal chain 40 and the positioning anchor 41, which is simple and stable in structure. The assembly frame 39 provides a reliable connection point for the metal chain 40 and enhances the connection strength; the metal chain 40 can buffer external force impact while ensuring the connection, so as to avoid excessive pulling of the floating island; and the positioning anchor 41 penetrates into the water bottom to ensure the positioning effect of the floating island.

[0045] In a further preferred embodiment of the present application, a discharging passage is formed in the bottom of the pruning shell 6, and a limiting block is fixed on the guide plate 30

[0046] In the embodiment, after the cutter head 7 rotates to cut the roots of aquatic plants in the trimming shell 6, the trimmed roots fall through the discharge channel at the bottom of the trimming shell 6. During the transverse movement of the trimming shell 6 along the guide plate 30, the limiting blocks on the guide plate 30 limit the movement of the trimming shell 6 to prevent the trimming shell 6 from moving excessively, ensure that the trimming shell 6 stops at the accurate trimming position, and ensure that the trimming shell 6 can return smoothly after the trimming work is completed. When the trimming shell 6 is in the appropriate position, the crushing teeth 37 crush the roots in the discharge channel, and the crushed roots fall into the water through the through hole in the floating island plate 1.

[0047] The discharge channel provides a clear discharge path for the trimmed roots, avoiding the accumulation of roots in the trimming shell 6 and affecting subsequent trimming work. The limiting blocks provide precise limiting for the movement of the trimming shell 6.

[0048] In a further preferred embodiment of the application, the placing rack 3 is provided with a placing opening that is adapted to the cultivation basket 4.

[0049] In the embodiment, the cultivation basket 4 is aligned with the placing opening on the placing rack 3 and directly placed therein. Since the placing opening is adapted to the cultivation basket 4, the cultivation basket 4 can be securely clamped in the placing opening. When it is necessary to lift the cultivation basket 4 for hydroponic or trimming operation, the placing rack 3 moves under the drive of the lifting mechanism, and the cultivation basket 4, due to the adaptive relationship with the placing opening, stably lifts together with the placing rack 3 without shaking, deviation, or the like.

[0050] In a further preferred embodiment of the application, the placing rack 3 is provided with a positioning slot symmetrically formed thereon, and the cultivation basket 4 is fixed with a positioning block that can be inserted into the positioning slot.

[0051] In the embodiment, when the cultivation basket 4 is installed, the positioning block on the cultivation basket 4 is aligned with the positioning slot on the placing rack 3 and vertically inserted downward. The adaptive design of the positioning block and the positioning slot enables the cultivation basket 4 to be accurately installed on the placing rack 3. When the placing rack 3 moves up and down under the drive of the lifting mechanism, the positioning block is securely clamped in the positioning slot, ensuring that the cultivation basket 4 stably lifts together with the placing rack 3 without displacement or shaking during the lifting process, and ensuring that the aquatic plants are always in a stable state.

[0052] The positioning slot of the placing rack 3 and the positioning block of the cultivation basket 4 are cooperatively designed to enhance the stability and accuracy of the installation of the cultivation basket 4. The symmetrically distributed positioning slot and positioning block form a double fixing effect, which can better resist external interference and avoid loosening of the cultivation basket 4 when the floating island shakes or lifts.

[0053] In a further preferred embodiment of the application, the placing rack 3 is provided with a threaded hole adapted to the first screw rod 20 and a guide hole adapted to the guide rod 21.

[0054] In the embodiment, when the motor 8 starts, the first screw rod 20 is driven to rotate by the clutch mechanism. Since the first screw rod 20 is matched with the threaded hole, when the screw rod rotates, the placing rack 3 moves up and down along the axial direction of the screw rod. At the same time, the guide rod 21 is tightly matched with the guide hole, which provides guidance for the movement of the placing rack 3, limits the movement of the placing rack 3 to a fixed direction, and ensures that the placing rack 3 stably and accurately rises and falls, thereby smoothly switching the cultivation basket 4 between the water culture position and the pruning position.

[0055] In the further preferred embodiment of the application, the floating island plate 1 is provided with a through hole, the size of the through hole is matched with the outer diameter of the cultivation basket 4, and the bottom of the cultivation basket 4 is provided with a water-permeable mesh structure.

[0056] In the embodiment, the placing rack 3 drives the cultivation basket 4 to rise and fall, and the cultivation basket 4 enters and exits through the through hole on the floating island plate 1. Since the size of the through hole is matched with the outer diameter of the cultivation basket 4, the cultivation basket 4 can smoothly pass through the through hole during the rising and falling process and will not shake greatly. When the cultivation basket 4 is in the water culture position, the plant root system is immersed in water, and the water-permeable mesh structure at the bottom of the cultivation basket 4 allows water to freely enter and exit, ensuring that the root system of the aquatic plant can fully contact the water and absorb nutrients; when the root system is pruned, the pruned root system falls through the water-permeable mesh and enters the water through the through hole, thereby providing food for aquatic organisms.

[0057] In order to further improve the use effect of the device, in addition to the above-mentioned scheme, the present scheme further has the following embodiments:

[0058] In another embodiment of the application, the pruning mechanism further comprises a root system treatment mechanism, which comprises: a rotating rod 36 assembled on the rotating rod 36 fixed in the discharge channel; a plurality of crushing teeth 37 fixed on the rotating rod 36 and the inner wall of the discharge channel, the crushing teeth 37 being arranged alternately for crushing the pruned plant root system; and twelfth bevel gears 38 fixed on the rotating rod 36 and the second transmission rod 15 respectively and meshing with each other.

[0059] In the embodiment, when the cutter head 7 completes the pruning of the aquatic plant root system, the pruned root system falls through the discharge channel at the bottom of the pruning shell 6. At this time, the second transmission rod 15 rotates under the driving of the rotary driving mechanism, and the twelfth bevel gears 38 on the second transmission rod 15 drive the twelfth bevel gears 38 on the rotating rod 36 to rotate, so that the rotating rod 36 starts to rotate. The rotating rod 36 cooperates with the crushing teeth 37 arranged alternately on the inner wall of the discharge channel to crush the falling root system, and the crushed root system particles are smaller, which fall into the water through the through hole of the floating island plate 1 to provide food for aquatic organisms.

[0060] The root system processing mechanism utilizes transmission bevel gears and staggered crushing teeth 37 to realize automatic crushing processing of the pruned root system. Through linkage with the rotary driving mechanism, the rotating rod 36 can be driven to rotate by means of the existing transmission structure without an additional power source, thereby reducing equipment cost and energy consumption. The staggered crushing teeth 37 increase the crushing area and intensity of the root system, and compared with a single crushing structure, the root system can be crushed into fine particles more quickly and effectively, thereby improving the root system processing efficiency.

[0061] In another embodiment of the present application, the floating island plate 1 is provided with a connecting assembly, which comprises groove blocks 42 and plug-in blocks 43 fixed on both sides of the floating island plate 1 respectively. The plug-in blocks 43 on two adjacent floating island plates 1 can be inserted into the corresponding groove blocks 42, and the groove blocks 42 are provided with fasteners 44 for limiting the plug-in blocks 43. The fasteners 44 are various, and in addition to bolts, they can also be flexibly selected according to different use scenarios and needs. If fast connection and disassembly are pursued, a buckle type fastener can be selected. The staff only needs to simply buckle or open to realize the connection and separation of the floating island plates, greatly improving the operation efficiency. When there is a certain requirement for sealing, a buckle type fastener is a good choice. Its unique clamping structure can not only ensure stable connection, but also prevent water and the like from entering the connection part to a certain extent. For situations that need to bear a large pulling force and impact force, a pin type fastener can ensure that the floating island plates are still closely connected under complex water environment due to its good shear resistance and tensile strength.

[0062] In the present embodiment, two landscape ecological floating islands are brought together, the plug-in block 43 on one of the floating island plates 1 is aligned with the groove block 42 on the adjacent floating island plate 1, and then it is inserted with force. After the plug-in block 43 is completely inserted into the groove block 42, the plug-in block 43 is limited and fixed by using the fastener 44, so as to ensure that the two floating island plates 1 are stably connected together. In this way, according to actual needs, a plurality of landscape ecological floating islands can be combined into floating island arrays of different scales and shapes. Through free combination of floating islands, the scale and layout of the floating islands can be flexibly adjusted according to the water area, ecological restoration needs and landscape design requirements, the coverage range of the floating islands is expanded, and the effect of purifying water quality and improving the ecological environment is enhanced. At the same time, the modular connection mode also facilitates the transportation, installation and later maintenance of the floating islands, and reduces the use cost.

[0063] In summary, compared with the related art, the floating island plate 1 is matched with the floating box 35 to provide buoyancy support, the installation frame 2 and the placement frame 3 are matched with the lifting mechanism to realize switching of the cultivation basket 4 between the water cultivation position and the pruning position, the pruning mechanism in the shell 5 is used, the translation mechanism and the rotary driving mechanism are used to drive the pruning shell 6 and the cutter head 7 to complete automatic pruning of the root system, the pulverizing tooth 37 in the root system processing mechanism is used to pulverize the pruned root system, ecological circulation of the water body is promoted, the positioning anchor 41, the metal chain 40 and the assembly frame 39 at the bottom of the floating island plate 1 are combined to ensure stability of the floating island, and the connecting assembly is used to realize flexible splicing of multiple floating islands. The problems of inconvenience in pruning of the root system of the traditional floating island are solved, the labor cost is reduced, and the management efficiency is improved.

[0064] In several embodiments provided in the present application, it should be understood that the disclosed device can be implemented in other ways.
